Extremism is a clear threat to the security of the United States and its allies. Assistance and development programs can potentially counter extremist messaging and, subsequently, the recruiting efforts of violent extremists. It may be most useful to view violent extremism through the prism of counterinsurgency. Department of Defense counterinsurgency doctrine, experience, and assets can substantively assist in this effort. This paper suggests that to enhance effectiveness, the United States Government should systemically integrate all entities into cohesive, holistic assistance and development programs which can undermine worldwide extremism. The paper examines efforts in Yemen, Lebanon, and Mauritania to help identify methods that may be more widely applicable.
